safety envelopes, and it consists of certainv novel features of construction, combination and arrangement of parts hereinafter described and claimed. L

'The object of the invention is to provide a simple and inexpensive device of this character, which may be securely locked or'sealed,

so that its contents can only be reached by tearing it open. v

The above and other objects, which will appear as 4the nature of my invention is better understood, are accomplished by means of the construction illustrated in the accompanying drawings ,in which Figure 1 is a plan view of the blank from which the improved envelope is made; Fig. 2 is a perspective view of the envelope showing it partially open, ready to receive its contents; Fig. 3 is a central transverse sectional view through the same in the position shown in Fig. 2; Fig. 4 isy a similar view,

taken in a plane adjacent to fone of the ends -of the envelop; Fig. 5 is a longitudinal sec- 35 tional view; Fig. 6 is a central transverse sectional view, showing, the envelope locked or sealed; and Fig. 7 is a detail section on ,an enlarged scale of one of the selfflocking fasteners.

The envelope is made from the single blank lshown in Fig. 1 of the drawings, and mav be composed of any suitable material. The blank comprises a front portionn 1, a back portion'2, two flaps 3, which are adapted-to form a central partition in the envelope, and a sealing or locking flap 4. The parts 1, 3, A3, 4, are dis osed at the sides andends lof the back 2 an are adapted to be folded over upon the same along the dotted lines shownl in Fig. 1. The flaps 3 are substantially recltangular in form and of such length as to overlap each other, as shown at 5, when folded over uponV the back 2 to form a central partition in the envelope. These flaps are adapted to have theiroverlapping ends pasted or otherwise united, and at their bottom edges are formed sea' adapted to be bentaleng the dotted linos vshown in Fi 1, and to bepasted upon the inner face o the back 2, asseen in Figs.3 and4. Y

The front 1 has at its ends sealing iaps 7, adapted to be bent over u on the dotted lines shown' in Fig. 1, an to be sealed upon the outer face of thev baek 2, as shown inFig. 5. Along the free longitudinal edge of the front 1 is formed a re-enforcing band hng flaps 6,

8, which is separated fromthe front by a slot 9, which extends between oints adjacent to the ends of the same, so t at the band 8 is only connected to the .front 1 by two necks 10. The band 8 is ada ted to be folded over upon the inner face o the central partition formed by the .flaps 3 and to be asted thereto after the members 11 of selfocking fasteners have been passed through` or secured in the s'aid artition adjacent to its upper free edge. T e fastening members 11 are adapted to be engaged bycoacting members 12, which are carried by a similar band upon' the sealing and locking flap 4, which latter is adapted to be inserted between the'outer face of the artition and the inner-face of the front 1. 'Ehe flap 4 is re-enforced by a band l'formed preferablyby doubling the flap uppn itself, and the fasteners l2 are passed t 4ough the portion 13 or secured therein before the latter is pasted j, upon the inner face ofthe flap 4. The latter is 'of slightly less length than the slot 9, so

that it may be readily inserted therethrough and between the partition and the front 1. At eachend of the flap 4 are formed on the back 2 small ton ues 14, which may be folded into the poc et between the back and the artition and pasted thereto if desired.

hile anyform of self-lookin fastening device may be employed, Ivpre erably use one consisting of two members, which when snapped together cannot be opened. A fastener of this character is shown in Figure 7 of the drawings and it consists of the member 11, which has a pointed head 15 adapted to enter between resilient jaws 16 formed or providedin the coacting-member 12, its removal therefrom being prevented by the envwith the jaws 16, as clearly shown 1n Fig. 7.

Ani number off these resilient stud andsoc e t fasteners may be employed, and they lOO gagement of a' shoulder 17 upon said head 15v l IlO may be arranged in any suitable mannerVV Y upon the two parts to be locked together.

I ing the latter.

and the minor details of construction may-be l The construction, use and advantages of the invention will be readily understood from the foregoing description, taken in connection with the accompan in drawings. It will be seen that When tli'e lank l-has been made up into the envelope shown in Fi 2, as reviously described, the enve ope may e eifectivel locked or sealed, after its contents have een placed in the compartment or space between the back 2- and the central partition, by first bending.

the flap 4 into the space between the parti- 'tion and the front 1 and snap ing the socket members 12 of the fastening evice over the stud members 11. When the fastenersv are once closed, it will be impossible to remove the dontents of the envelope Without destroy- To further seal the envelope, the fla 4 may be glued or pasted tothe inner face oi the front 1 after the fasteners 'have been closed. If desired, suitable gum or paste may be provided u on either the inner face of the front or said ap to permit of this sealing.

Various changes'in the form, proportion lresorted to Without departing from the prinnecks and separated by a slot, said band being adapted to be sealed to said partition, a flap on said back-having ,a reenforcing band and coacting fastening members carried by said back flap and said partition.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
